Frontly - Create Dynamic App Pages Using Block Versions & Local State
Summary
TLDRIn this tutorial, Patrick demonstrates how to utilize block versions and local state variables in Frontleaf to create responsive interfaces that update in real-time. He guides viewers through setting up a button that toggles between 'inactive' and 'active' states upon clicks. Patrick further explains how to manage local state values, which can control the visibility of elements like tables based on specific conditions. The video is a practical guide to building dynamic and interactive web applications.
Takeaways
- đ ïž Patrick demonstrates how to use block versions and local state variables to create responsive blocks that update in real-time.
- đ He starts by creating a button with a default state of 'inactive' and shows how to change it to 'active' upon user interaction.
- đ§ Patrick explains the concept of block versions as settings that are active only when the version is selected in the editor.
- đ He introduces local state as a way to store values that can be accessed and modified throughout the app.
- đ Local state is accessed using a key-value pair, where 'status' is the key used in the tutorial.
- đš Patrick shows how to set conditions for block versions to determine when they should appear based on the local state.
- đ He creates a click action to toggle the local state value between 'active' and 'inactive', which in turn changes the button's state.
- đ The tutorial also covers how to use local state to control the visibility of other elements, like a table, based on the state of the button.
- đĄ Patrick suggests using a text block to display the local state value during development for easier debugging and tracking.
- đ The features discussed are powerful for creating responsive and interactive elements in apps.

What action does Patrick add to the button to toggle its state?
-Patrick adds a click action to the button that updates the local state variable 'status' to 'active' or 'inactive' depending on the current state.
How does Patrick use local state to control the visibility of a table in the app?
-Patrick uses a display condition on the table block to show or hide it based on the value of the local state variable 'status'. If 'status' equals 'active', the table appears; otherwise, it remains hidden.
What additional tip does Patrick give for managing local state during development?
-Patrick recommends adding a text block to the page to display the value of the local state, which helps in keeping track of the current state during development.
What is the purpose of using block versions and local state according to the video?
-The purpose of using block versions and local state is to create responsive and interactive elements in the app that update in real time based on user actions, enhancing the user experience.
